Sonic, Y/N, and Elise are walking in Soleanna and they suddenly stopped. Sonic notices an attack coming towards them and, grabbing Y/N and Elise, jumps to avoid it. Elise cries out as the attack explodes harmlessly where they were. The source of the attack soon descends to confront them. Y/N looked up to see Silver who's floating down.

"I've been looking for you. You're the Iblis Trigger. Your actions will condemn us all." Silver said, pointing at Sonic.

"Who are you?"

"My name is Silver. For the future of the world, I will destroy you!"

Y/N steps forward in front of Sonic.

"Whoa, hey! Let's not go there! Sonic did nothing wrong! What did he ever do to you? And what do you mean by Iblis Trigger?"

"Stay back, Y/N. He's dangerous. He will destroy you."

"No way! Not until you explain to me on what's going on. How do you even know my name?"

"That's none of your concern. All I'm asking you is to stay back and let me kill him. This is for your own safety and good."

"Never!! If you're going to hurt my brother, then you're going have to go through me!"

Y/N took out her katana and her whip, glaring at Silver. Silver sighed.

"Fine. So be it."

"Stay back, Elise." Y/N said.

Elise nodded and backed away. Sonic joins Y/N as they both got into their fighting stance, facing Silver.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"Time for you to disappear, Iblis Trigger!" Silver declared.

"Doesn't look like you're good to talk." Sonic said, stretching himself.

"No kidding." Y/N said, pointing her katana forward while spinning her whip.

Silver started levitating chairs and tables, using his psychokinetic. They quickly dodged them all. Suddenly, Sonic was frozen as he was being held in the air with psychokinetic covering him up.

"It's no use!"

Y/N growled, seeing Silver was about to throw a giant crate towards Sonic as he yelled.

"Take this!"

She quickly threw her whip towards Silver catching him off-guard. He quickly stopped the whip as it froze in the air, letting go of Sonic in the process as Y/N sliced off the wooden crates. Sonic nods at Y/N in appreciation as Y/N faced Silver who's surprised. She held her crystal necklace, activating her power as she floated up in the air and glowed white.

"How did you--"

"You're not the only one with power."

With that, she brought her whip back to her and covered Sonic in a barrier to protect him. Silver tried to attack him, but it was deflected back. He even tried using psychokinetic and it didn't faze Sonic one bit. Amy wasn't kidding that Y/N is very tough to fight against. He dodged the katana that was thrown towards him and ducked when it tried to stab him from behind with the help of the crystal.

Sonic runs towards Silver and spin dashed him, hitting him. Silver groaned in pain as his psychokinetic was turned off. Y/N quickly flies down and kicks Silver in the back. Silver was thrown against the table as the chairs clattered. Y/N and Sonic waited for another attack as Silver attempt to trap Sonic in the psychokinetic, but Y/N's protective shield prevented him from doing that. Sonic zooms in and spin dashed Silver again and hit him. Y/N rocket roller skates at Silver as he send out his psychokinetic blast towards her who blast him back using her crystal.

"That ain't gonna work, Silver!" she said and was suddenly levitated in the air.

She cursed herself that she didn't turn on a shield on herself and was focusing on protecting her brother. Y/N was then flown against the wall. She groaned, feeling a hard impact from her back.

"Sis!!"

"Sorry, Y/N..."

Silver then levitated the chairs and tables and threw them towards Sonic as the shield had died down afted she got hit. Sonic quickly dodges them by running around. He runs as fast as he can while dodging many objects. Sonic then spin dashed Silver again after coming close to him as Silver groaned again. Sonic did it again, trying to tire him down when he was levitated again by Silver's psychokinetic and was thrown against the wall.

"Take this!"

Y/N got up and glared at Silver who's focusing on Sonic once again. She rocket roller skates and then jumps over Silver and lands perfectly in front of him.

"What?"

Y/N then punches him in the chin, throwing him backward. Sonic saw this as an opportunity and runs in and kicks Silver down.

"No! Ow..."

Silver was now down as he fell to the ground. Sonic and Y/N gave each other a smile. Silver is weak from their fight and Elise is looking at him.

"Yo, Silver. You okay?" Y/N asked, looking down at him.

"Hey." Sonic said.

Silver psycho-kinetically attacks Sonic, knocking him towards a building where Sonic slams hard against the stone and falls down to the ground on his knees after hitting it.

"Sonic!!" Y/N gasped.

Elise looks on with worry as Sonic tries to catch his breath as Silver approaches him. Y/N immediately goes in front of Sonic protectively.

"Hmph! Is this a joke? How could someone like you cause the destruction of our world?"

What they didn't know is the two robotic hands appear behind Elise.

"What do you... mean?" Sonic asked in confusion.

"Yeah, what are you talking about? Are you saying that Sonic's an enemy? I don't see any threat from him. Even if he did, he would never hurt anyone." Y/N said, pointing at Silver accusingly.

"It doesn't matter. For the sake of the future, the Iblis Trigger must be destroyed!"

"You wanna go?!"

Y/N puts up her fists. Suddenly, Elise screams. Sonic, Y/N, and Silver see the Egg Mobile capturing her.

"Elise!!" Y/N shouted.

"Wait!" Sonic shouted.

Sonic and Y/N tries to go after Elise but Silver attacked Sonic again in the back, knocking him down. Y/N stopped to see Sonic down again. She had enough of that Silver guy.

"Don't you dare turn your back on me! It's time I finally put an end to this!"

Just as Y/N was about to stop him again, Amy appears.

"Stop!"

"Amy!" Y/N exclaimed in surprise.

"Amy? Get out of my way, Amy! This is my mission!" Silver said.

"Absolutely not!" Amy shook her head.

Silver grunts in frustration. Sonic stands up.

"Thanks Amy. I appreciate it."

Sonic begins to flee and chase the Egg Carrier. Y/N was about to stay with Amy when Amy told her.

"Leave it to me, Y/N. Don't worry. You go worry about Sonic."

"Thank you, Amy. I'll see you there." Y/N nodded and glared at Silver. "You're going to regret this, Silver. If I see you try to kill Sonic again, you're dead."

With that, Y/N goes after Sonic. Sonic keeps running to catch up to Eggman and Elise with Y/N behind him while Amy holds off Silver.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Amy is still In Silver's way in Soleanna.

"The person you were looking for was Sonic? Were you planning to kill him?"

Silver ponders for a bit then speaks angrily.

"He's responsible for destroying my world."

"That's crazy!"

Amy points at him and accuses him.

"Sonic would never do that!"

"But it's true! In the near future, his actions will cause the devastation of my world. So I must..."

"No! I don't believe it. Even if that was true. If I had to choose between the world and Sonic, I would choose Sonic!"

Amy runs off in disbelief, and Silver tries to explain, but stops. He hangs his head down in confusion, wondering what to do. What's worse is that he made an enemy of Y/N and now she hates him.
